Benefits of technology

[0014] In one aspect, the present invention is a lamp which can be easily assembled with a lamp holder. The lamp includes a lamp tube, an electrode disposed at an end portion of the lamp tube, and a lamp lead. The lamp tube may be of a type that contains a discharging gas. The electrode is inside the lamp tube. The lamp lead includes a connection portion and a securing portion. The connection portion extends from the electrode to the securing portion, wherein the securing portion is located outside the lamp tube.
[0015] In another aspect, the present invention is a lamp holder that may be easily assembled with a lamp and a power supply substrate. The lamp holder includes a body and a power supply member. The body includes a lamp support portion capable of supporting an end portion of a lamp. The power supply member is fixed to the body and welded to a voltage supply wire for providing a voltage to an electrode that is disposed at the end portion of the lamp.
[0018] In yet another aspect, the present invention is a power supply module that lends itself to efficient fabrication. The power supply module includes a lamp holder and a power supply substrate. The lamp holder has a body and a power supply member, wherein the power supply member includes a connection terminal coupled to the body and a power supply terminal capable of coupling to a lamp. The power supply substrate makes contact with the connection terminal.
[0022] The invention enhances the electrical connections among the lamp, the lamp holder and the power supply substrate without using soldering, and allows easy fabrication of a backlight assembly or a power supply module including a lamp, a lamp holder and the power supply substrate.
[0023] The invention further improves the rework efficiency of the power supply module of the backlight assembly by allowing the power supply substrate to be separated from the power supply module or the backlight assembly without detaching the lamps from the lamp holders.

Problems solved by technology

However, the numbers of the lamps and lamp holders used in the backlight assembly increase with the size of the display panel, and a high number of lamps and lamp holders begins to pose disadvantages.
For example, with many lamps and lamp holders, the display device becomes heavier and fabrication time lengthens.
The soldering step tends to increase the time for fabricating the backlight assembly and does not always securely attach the leads of the lamps to the lamp holders.
Additionally, the lamps may be damaged during the soldering process.
Furthermore, the connector between the lamp holders and the wire or the PCB may be broken in the operation of the backlight assembly.

Abstract

A lamp, lamp holder, and a power supply substrate that allow easy fabrication of a backlight assembly or a power supply module for a display device are presented. The lamp includes a lamp tube and an electrode that extends outside the lamp tube to form a lamp lead. The lamp holder includes a body for holding the lamp tube and a power supply member for providing voltage to the lamp lead. A power supply module includes a power supply substrate combined with a lamp holder holding the lamp. The lamp holders are fixed to fixing portions of the power supply substrate or to fixing holes of a connection plate. As the design allows easy separation of the lamp holders from the power supply substrate, building a backlight assembly or a display device is facilitated.
